This PR is NOT a fix for #105573. Instead, it uses Rust CI to build code that triggered #105573 for me locally. (As per https://rustc-dev-guide.rust-lang.org/contributing.html#ci: "perfectly fine (and even encouraged!) to use the CI to test your changes if it can help your productivity").

Please don't review this PR. If possible, assign it back to me, or label it somehow so it won't waste time of reviewers.
Thank you in advance.
